Comet C/2013 A1 Siding Spring will miss Mars by only about 88,000 miles (139,500 kilometers). That is less than half the distance between Earth and its Moon and less than one-tenth the distance of any known comet flyby of Earth. The comet’s nucleus will come closest to Mars at about 2:27 p.m. EDT (11:27 a.m. PDT), hurtling at about 126,000 mph (56 kilometers per second), relative to Mars… [More about the comet here, and more about the briefing here.]
